Application filed April 1, 1914. Serial No. 828,831.

To all 107mm it may concern c it known that I, WILLIAM M. SULLI- VAN, a citizen of the United States, residing a Bienville, in the parish of Bienville and State of Louisiana, have invented certain new and useful Improvements in Metallic Railroad-Ties; hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in. the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in metallic railroad ties, and has for its principal object which is particularly adapted for use on bridges and similar Another object of the invention is to pro vide a tie in which it is possible to substitute portions thereof so as to eliminate the necessity of renewing the entire tie should further ob ect of the invention is to provide a novel means for securing the rails preventing said rails from spreading.

Still another object of the invention is to provide a means for firmly securing the tie to tl securing means suitable ports of all widths and With these and other objects in view, the invention consists in the novel combination and arrangement of parts which will be more fully described in the following specification and accompanying drawings, in which,

Figure 1 is a top plan of a tie constructed in accordance with this invention, Fig. 2 is a side view in elevation of a tie constructed in accordance with this invention, Fig. 3 is a longitudinal sectional view of a fragment of a tie constructed in accordance with this invention, Fig. 4 is a transverse sectional view taken on line H of Fig. 3, and Fig. 5 is a bottom plan view of a fragment of a tie constructed in accordance with this invention, clearly illustrate the means or securing the same to the bridge structure.

Referring now to the drawings by charicters of reference, the numerals 1 and 2 :lesignate as entireties the two cooperating elements forming the main body portion of a tie, each of which is provided with the slot 3 substantially centrally of its longitudinal extremities. A depending lug i is formed on each of the members 1 near their and (5 are formed on the members 1 and 2 respectively and are arranged to cooperate with each other form interlocking portions and hold the two separate elements rigidly in place. Near the outer ends of each of the elements is provided the rail engaging member 7 whic is provided with the slot 8 which is arranged to receive the outer flange tie. Intermediate the ends and 6 is of each of the extensions 5 provided the aperture 9 which is arranged to receive the bolt 10 which cooperates with the extensions in rigidly securing the two separate elements 1 and 2 in place.

Cooperating with the member 7 which is provided with the slot 8, in holding the rails in position on each of the elements, is

provided a pair of rail ange engaging members 11 each of which comprises the ody portion 12 having the flange overlying portion 13 formed thereon. The said body portion 12 is provided with a centrally located aperture 14- through which the bolt 15 is ad apted to extend. These bolts 15 extend through the slots 3 and through the apertures 14- and are provided with suit able nuts by means of which they may be firmlv secured in place and the rail securing elements may be held against movement thereby. The end of the rail securing element 11 opposite the extension 13 is provided with a beveled face 16 which is arranged to cooperate with the beveled face 17 formed on the end of the longitudinally extending bar 18. This longitudinal bar 18 is provided at its opposite extremity with the beveled face 19 which is arranged to cooperate with the beveled face of the opposite rail fastening element 11 as clearly shown in Fig. 1. Centrally located with relation to the bar 18 is provided the aperture 20 through which the bolt 10 which extends t rough the aperture 9 is adapted to pass.

hus it will be seen tiat when said bolt is secured in place the rigid bar will be held against the upper face of the cooperating members 1 and 2 and accidental displacement of said cor'iperating members will be thereby eliminated.

In order to provide a means for securing the tie in place on the structure, the downward extension 4: is formed on the under side of the tie and is arranged to cooperate with the angle plate 21 having the depending portions 22 formed integral therewith which is arranged to engage one side of the structure, while the lug l engages the opposite side thereof. A suitable slot 23 is formed in the plate and is arranged to be adjusted longitudinally with relation to the t It will be apparent from the foregoing that in use the rails are placed in positlon on the tie as illustrated in Fig. 2 and the rail flange engaging members force into frictional engagement with the inner flanges of the rail. The bar 18 is then placed in posi tion and so slid that the angle faces 17 and 19 will engage the angle faces 16 on the members 11 thereby causing the same to firmly grip the rails and prevent said rails from becoming accidentally displaced.

Should any portion of the tie become damaged, it will be apparent that the section ma be removed and a perfect section substituted therefor without necessitating any great loss of time or trouble in making the substitution.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the invention as defined in the appended claim.

Copies of this patent may be obtained for five cents each, by addressing the Having thus described my invention, I claim:

In a device of the character described, a railroad tie comprising a pair of cooperating members, each of said cooperating members being provided with a substantially centrally located slot, tongues formed on the ends of the cooperating members and adapted to cooperate with each other to hold the cooperating members in position, rail flange engaging members formed integrally with the cooperating members near their ends oposite the tongues, rail flange engaging members slidable on the cooperating members and adapted to cooperate with the first mentioned rail flange engaging members, bolts extending through the slidable flange engaging members and through the slots to hold the flange engaging members in their proper position, beveled faces formed on the inner ends of the flange engaging members, a longitudinal bar slidably mounted transversely of the tie, said bar being provided with beveled faces adapted to cooperate with the beveled faces on the rail engaging members, and a versely slidable bar and arranged to hold the bar in its adjusted position, and thereby hold the rail flange engaging members against movement.

In testimony whereof I allix my signature in presence of two witnesses.
